DETAILED DESCRIPTION

[0031] The following is a further description of the specific implementation of the present invention in conjunction with the accompanying drawings and embodiments. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and cannot be used to limit the protection scope of the present invention.

[0032] like Figure 1-Figure 9 As shown, the oriented silicon steel continuous annealing and brushing device of the utility model comprises:

[0033] A transmission component 1, the transmission component 1 is used to convey a steel belt 2, and the transmission path of the steel belt 2 includes a horizontal brushing section;

[0034] A scrubbing assembly, the scrubbing assembly comprises a scrubbing pool 3, a scrubbing lower roller 4, a scrubbing upper roller 5 and an infusion assembly 6. The scrubbing lower roller 4 and the scrubbing upper roller 5 both extend in a width direction parallel to the steel strip 2 and rotate around their own axis. The scrubbing lower roller 4 and the scrubbing upper roller 5 are respectively in contact with the upper surface and the lower surface of the scrubbing section. The scrubbing lower roller 4 is a hollow floating roller with a bottom arranged in the scrubbing pool 3. The scrubbing upper roller 5 comprises a hollow upper roller body 51 with a surface densely covered with through holes 511 and an upper sponge sleeve 52 with a sealing sleeve arranged outside the upper roller body 51. The infusion assembly 6 is used to replenish the scrubbing liquid in the scrubbing pool 3 into the upper roller body 51. Two scrubbing assemblies are provided, which are sequentially distributed along the transmission path of the steel strip 2. The scrubbing pool 3 adjacent to the feeding side of the steel strip 2 is an alkali washing pool, and the scrubbing pool 3 adjacent to the discharging side of the steel strip 2 is a water washing pool.

[0035] Two squeezing assemblies 7 are respectively adjacent to the discharge side of the two brushing assemblies, and each squeezing assembly 7 includes two squeezing rollers 71 respectively abutting against the upper and lower surfaces of the brushing section. The two squeezing rollers 71 rotate around their own axis and the axial direction is consistent with the width direction of the steel belt 2.

[0036] Specifically, in the utility model, the transmission component 1 mainly includes a unwinding roller and a winding roller, which are driven to rotate by two driving devices respectively. The steel belt 2 is wound on the unwinding roller and the winding roller. The rotation of the unwinding roller and the winding roller drives the steel belt 2 to rotate. In the transmission path of the steel belt 2, one end is a brushing section, and the brushing section is horizontally arranged.

[0037] When the steel strip 2 passes through the brushing section, two brushing assemblies are used to perform alkali washing and water washing in sequence. After the alkali washing, the steel strip 2 is squeezed by the squeezing assembly 7 adjacent to the feeding side, and then washed with water. After the water washing, the steel strip 2 is squeezed by the squeezing assembly 7 adjacent to the discharging side, and thus the brushing treatment of the steel strip 2 is completed. The brushing device of the utility model is mainly used for brushing oriented silicon steel and oriented electrical steel of the same type as oriented silicon steel to remove residual oil, iron powder and other loose impurities on the surface, so as to ensure the subsequent treatment of oriented silicon steel and improve product quality.

[0038] Different from the prior art, in the brushing assembly of the utility model, the upper brushing roller 5 and the lower brushing roller 4 are both hollow structures, wherein the lower brushing roller 4 is a floating roller, floating above the liquid surface of the brushing liquid in the brushing pool 3, and can rotate around its own axis. During the transmission of the steel belt 2, the lower brushing roller 4 abuts against the lower surface of the steel belt 2, and the lower brushing roller 4 rotates around its own axis. Under the influence of buoyancy, the lower brushing roller 4 generates upward pressure on the lower surface of the steel belt 2, and the lower brushing roller 4 rotates around its own axis, thereby achieving a good brushing effect on the lower surface of the steel belt 2.

[0039] Above the steel strip 2, the upper scrubbing roller 5 includes an upper roller body 51 and an upper sponge cover 52. The upper roller body 51 is hollow and has through holes 511 on its surface. The scrubbing liquid in the scrubbing pool 3 is transported into the inner cavity of the upper roller body 51 through the infusion assembly 6. The scrubbing liquid penetrates into the upper sponge cover 52 through the through holes 511. The circumferential outer edge of the upper sponge cover 52 abuts against the upper surface of the steel strip 2. Thus, as the upper scrubbing roller 5 rotates, the scrubbing liquid infiltrated into the upper sponge cover 52 contacts the upper surface of the steel strip 2 to clean the upper surface of the steel strip 2. Compared with the prior art, the scrubbing device does not need to be provided with an immersion tank and a spray assembly, thereby simplifying the structure while ensuring the scrubbing effect on the upper and lower surfaces of the steel strip 2, and shortening the transmission path of the steel strip 2, thereby reducing the occupied space of the device and simplifying the device cost.

[0040] In order to conveniently discharge the scrubbing liquid in the scrubbing pool 3, a drain pipe 31 is connected to the bottom of the scrubbing pool 3, and a valve 32 is connected to the drain pipe 31. After the device runs for a period of time, the valve 32 is opened to conveniently discharge the scrubbing liquid in the scrubbing pool 3, and then the valve 32 is closed. The scrubbing pool 3 adopts a top open structure, which is convenient for adding scrubbing liquid into the scrubbing pool 3.

[0041] A further improvement is that the upper scrubbing roller 5 is an upper pressure roller, and the upper scrubbing roller 5 is connected to an upper sliding seat 53 , and the upper sliding seat 53 slides vertically above the scrubbing pool 3 .

[0042] After adopting the above structure, when the upper scrubbing roller 5 cleans the steel belt 2, it slides down to the upper surface of the steel belt 2 by relying on the gravity of itself and the scrubbing liquid in the inner cavity, thereby ensuring the action force between the upper sponge sleeve 52 and the surface of the steel belt 2, thereby ensuring the scrubbing effect on the upper surface of the steel belt 2 after the upper scrubbing roller 5 rotates as the steel belt 2 is transmitted.

[0043] A further improvement is that the scrubbing lower roller 4 is connected to a lower sliding seat 43 , the scrubbing pool 3 is fixedly connected to a sliding rod 33 extending in a vertical direction, and both the upper sliding seat 53 and the lower sliding seat 43 slide on the sliding rod 33 .

[0044] The bottom end of the slide bar 33 is fixedly connected to the inner bottom wall of the scrubbing pool 3. The lower sliding seat 43 and the upper sliding seat 53 are both sliding sleeves, which slide on the slide bar 33 in the vertical direction. On the one hand, the structure is further simplified. On the other hand, it ensures that the axis line of the upper scrubbing roller 5 and the axis line of the lower scrubbing roller 4 are always in the same vertical plane. The upper scrubbing roller 5 presses down on the upper surface of the steel belt 2 by its own pressure and the gravity of the internal scrubbing liquid, and the lower scrubbing roller 4 presses upward on the lower surface of the steel belt 2 by its own buoyancy, thereby ensuring the scrubbing effect on the steel belt 2 in the scrubbing section.

[0045] A further improvement is that the scrubbing lower roller 4 includes a lower roller body 41 and a lower sponge sleeve 42 with a sealing sleeve arranged outside the lower roller body 41; the lower roller body 41 and the lower sponge sleeve 42 are provided with matching assembly ridges 44 and assembly grooves 45, and the assembly grooves 45 are through grooves extending along the axial direction parallel to the lower roller body 41.

[0046] The assembly groove 45 is arranged on the circumferential outer edge of the lower roller body 41, and the assembly ridge 44 is arranged on the circumferential inner wall of the lower sponge sleeve 42. Both are provided with four and are matched one by one. Through the matching assembly grooves 45 and assembly ridges 44, the synchronous rotation between the lower roller body 41 and the lower sponge sleeve 42 can be achieved. After the lower roller body 41 rotates around its own axis, the lower sponge sleeve 42 can absorb the scrubbing liquid in the scrubbing pool 3, and rotate synchronously with the lower roller body 41, while applying pressure to the lower surface of the steel belt 2, the lower surface of the steel belt 2 is scrubbed.

[0047] The specific structure of the upper brushing roller 5 and the lower brushing roller 4 can be referred to Figure 7-Figure 9 As shown, in the scrubbing lower roller 4, the lower roller body 41 is a cylindrical structure, with lower end covers 411 threadedly connected at both ends, a lower bearing 412 is provided on the outer side of the lower end cover 411, the outer ring of the lower bearing 412 is fixedly connected to the lower end cover 411 coaxially, and the inner ring is fixedly connected to the lower sliding seat 43.

[0048] In the scrubbing upper roller 5, the upper roller body 51 is a cylindrical structure, with upper end covers 513 threadedly connected at both ends. The circumferential outer edge of the upper roller body 51 is densely covered with through holes 511 connected to its own inner cavity. The upper end cover 513 is a tubular structure with one end closed and the other end open, and its open end faces the inner cavity of the upper roller body 51. The upper end cover 513 protrudes from the end surface of the upper roller body 51. An upper bearing 514 is arranged on the upper end cover 513. The inner ring of the upper bearing 514 is fixedly connected to the upper end cover 513 coaxially, and the outer ring is fixedly connected to the upper sliding seat 53.

[0049] A further improvement is that at least two upper scrubbing rollers 5 and lower scrubbing rollers 4 are provided and spaced apart along the length direction of the scrubbing section.

[0050] In the utility model, each brushing assembly is provided with two upper brushing rollers 5 and two lower brushing rollers 4, which are spaced apart along the length direction of the brushing section. By providing a plurality of upper brushing rollers 5 and lower brushing rollers 4, multiple brushing of the upper and lower surfaces of the steel belt 2 can be achieved, thereby improving the brushing effect.

[0051] A further improvement is that the circumferential outer edge of the upper roller body 51 is provided with a liquid inlet hole 512 connected to its own inner cavity, the infusion assembly 6 includes an infusion pump 61 and an infusion ring 62, the infusion ring 62 is sleeved on the outside of the upper roller body 51 and enclosed with the upper roller body 51 to form an annular infusion cavity, the infusion ring 62 is provided with an infusion port 621, the input end of the infusion pump 61 is connected to the scrubbing pool 3, and the output end, the infusion port 621, the infusion cavity and the liquid inlet hole 512 are connected in sequence.

[0052] Specifically, the input end of the infusion pump 61 is arranged in the scrubbing pool 3 and is gap-matched with the inner bottom wall of the scrubbing pool 3, and the output end is connected with a T-shaped infusion tube 63, one end of the infusion tube 63 is connected to the infusion pump 61, and the other two ends are respectively connected to the infusion ports 621 on the infusion rings 62 corresponding to the two scrubbing upper rollers 5; the upper end cover 513 protrudes from the upper roller body 51, and a partial annular array is distributed with liquid inlet holes 512, and both ends of the infusion ring 62 are integrally connected with sealing rings, and the liquid inlet hole 512 is located between the sealing rings at both ends, and the circumferential inner wall of the sealing ring is sealed with the circumferential outer edge of the upper end cover 513, so that the infusion cavity formed by the infusion ring 62 and the upper end cover 513 is connected between the liquid inlet hole 512 and the infusion port 621.

[0053] After adopting the above structure, the infusion pump 61 regularly extracts part of the scrubbing liquid from the scrubbing pool 3 and transports it through the infusion tube 63. The scrubbing liquid enters the infusion cavity through the infusion port 621, and is then transported to the inner cavity of the upper end cover 513 through the liquid inlet hole 512, and enters the inner cavity of the upper roller body 51 through the inner cavity of the upper end cover 513, so that the upper sponge cover 52 can absorb the scrubbing liquid through the through hole 511 to scrub the upper surface of the steel belt 2.

[0054] A further improvement is that the squeezing assembly 7 further includes a receiving pool 72 , which is connected to the scrubbing pool 3 , and the bottom of the receiving pool 72 is located directly below the two squeezing rollers 71 .

[0055] The projections of the two squeeze rollers 71 on the horizontal plane are located within the projections of the receiving tank 72 on the horizontal plane, so as to collect the scrubbing liquid dropped from the squeeze rollers 71 and the surface of the steel strip 2. The receiving tank 72 is fixed to one side of the scrubbing tank 3, and the receiving tank 72 and the scrubbing tank 3 are both provided with openings on both sides adjacent to each other, and the bottom of the receiving tank 72 is located on the upper side of the scrubbing tank 3, so that the scrubbing liquid received by the receiving tank 72 can flow into the scrubbing tank 3. On the one hand, the cleanliness of the scrubbing operation environment is ensured, and the scrubbing liquid is prevented from falling to the ground. On the other hand, the scrubbing tank 3 can recycle the scrubbing liquid, reduce the amount of scrubbing liquid, and save the scrubbing cost.

[0056] A further improvement is that a drying opening 73 is provided on the receiving pool 72 toward the circumferential outer edge of the squeezing roller 71 below the scrubbing section, the drying opening 73 is adjacent to the squeezing roller 71 , and a fan 74 is connected to the drying opening 73 .

[0057] Specifically, the air-drying port 73 is arranged on the inner wall of the receiving pool 72 away from the scrubbing pool 3. The air-drying port 73 is long and extends in a width direction parallel to the steel belt 2. An air-drying shell 77 is fixed on the outer wall of the receiving pool 72. The air-drying shell 77 and the receiving pool 72 are combined to form an air-drying chamber. The fan 74 is fixed under the receiving pool 72. Its input end is connected to the outside, and its output end is connected to the air-drying port 73 through the air-drying chamber.

[0058] After adopting the above structure, while the steel strip 2 is being brushed and the squeezing component 7 is squeezing the steel strip 2, the fan 74 is started, and after drawing in external air, it is transported to the air-drying port 73 through the air-drying chamber, so that the air-drying port 73 blows air toward the squeezing roller 71 under the steel strip 2, and while drying the scrubbing liquid on the surface of the squeezing roller 71, the scrubbing liquid in the receiving pool 72 can also be blown into the scrubbing pool 3.

[0059] In order to facilitate the drying of the surface of the squeeze roller 71 above the steel strip 2, the squeeze roller 71 is preferably an electric heating roller to facilitate the volatilization of the scrubbing liquid on its circumferential outer edge and maintain the dryness of the surface.

[0060] A further improvement is that the two squeezing rollers 71 are connected to two telescopic units 75 in a one-to-one correspondence, and each telescopic unit 75 is used to drive the corresponding squeezing roller 71 to move in a direction perpendicular to the width of the steel strip 2 to adjust the distance between the squeezing roller 71 and the scrubbing section.

[0061] Specifically, the telescopic unit 75 includes electric push rods disposed at both ends of the squeeze roller 71, the axial direction of the electric push rods is parallel to the vertical direction, the housing of the electric push rod located at the bottom is fixed on the receiving tank 72, and the housing of the electric push rod located at the top is connected to the receiving tank 72 through a fixing frame 76. The position of the squeeze roller 71 can be adjusted conveniently through the telescopic unit 75, thereby conveniently adjusting the extrusion force between the squeeze roller 71 and the steel strip 2.

[0062] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
